Im trying to get service on a new house and the registration system says “The address you entered could not be recognized”

Hello, Im trying to start a new internet service at the new house I am moving to. It is fairly new, (built less than 6 months ago) and I suppose it isn’t in your system yet. Is there anyone I can talk to to register this home and make it available for service. The error message that pops up when I type my address is as follows “The address you entered could not be recognized”.
